Validation Functions

Our active entity object will also give you access to our validation engine (cbValidation) by giving your ORM entities the following functions:

* Validate the ActiveEntity with the coded constraints -> this.constraints, or passed in shared or implicit constraints
* The entity must have been populated with data before the validation
* @fields One or more fields to validate on, by default it validates all fields in the constraints. This can be a simple list or an array.
* @constraints An optional shared constraints name or an actual structure of constraints to validate on.
* @locale An optional locale to use for i18n messages
* @excludeFields An optional list of fields to exclude from the validation.
boolean function isValid(
string fields="*",
any constraints="",
string locale="",
string excludeFields=""
* Get the validation results object. This will be an empty validation object if isValid() has not being called yet.
cbvalidation.models.result.IValidationResult function getValidationResults(){

Declaring Constraints

This makes it really easy for you to validate your ORM entities in two easy steps:

1) Add your validation constraints to the entity

2) Call the validation methods

Let's see the entity code so you can see the constraints:

component persistent="true" extends="cborm.models.ActiveEntity"{
// Properties
property name="firstName";
property name="lastName";
property name="email";
property name="username";
property name="password";
// Validation Constraints
this.constraints = {
"firstName" = {required=true},
"lastName" = {required=true},
"email" = {required=true,type="email"},
"username" = {required=true, size="5..10"},
"password" = {required=true, size="5..10"}

Validating Constraints

Now let's check out the handlers to see how to validate the entity via the isValid() function:

property name="messagebox" inject="[email protected]";
function index(event,rc,prc){
prc.users = getInstance( "User" ).list( sortOrder="lastName asc" );
event.setView( "users/list" );
function save(event,rc,prc){
event.paramValue( "id", -1 );
var oUser = getInstance( "User" )
.getOrFail( )
.populate( rc )
if( oUser.isValid() {;
flash.put( "notice", "User Saved!" );
relocate( "users.index" );
messagebox.error( messageArray=oUser.getValidationResults().getAllErrors() );
editor( event, rc, prc );
function editor(event,rc,prc){
event.paramValue( "id", -1 );
prc.user = getInstance( "User" ).getOrFail( );
event.setView( "users/editor" );
function delete(event,rc,prc){
event.paramValue( "id", -1 );
getInstance( "User" )
.deleteById( );
flash.put( "notice", "User Removed!" );
relocate( "users.index" );

Please remember that the isValid() function has several arguments you can use to fine tune the validation:

  • fields

  • constraints

  • locale

  • excludeFields

Displaying Errors

You can refer back to the cbValidation docs for displaying errors:

Here are the most common methods for retreving the errors from the Result object via the getValidationResults() method:

  • getResultMetadata()

  • getFieldErrors( [field] )

  • getAllErrors( [field] )

  • getAllErrorsAsJSON( [field] )

  • getAllErrorsAsStruct( [field] )

  • getErrorCount( [field] )

  • hasErrors( [field] )

  • getErrors()

The API Docs in the module (once installed) will give you the latest information about these methods and arguments.

Unique Property Validation

We have also integrated a UniqueValidator from the validation module into our ORM module. It is mapped into WireBox as [email protected] so you can use it in your model constraints like so:

{ username : { validator : "[email protected]", required : true } }
